During my time in the Navy submarine force, I worked with a handful of terrible leaders. But one leader in particular taught me more about how not to lead than anyone else. He wasn't a yeller. He didn't curse. He generally had a pleasant disposition. But two of his habits didn't just weaken trust. They ripped his team apart from the inside.

Habit One: He Never Took the Blame

The moment it was time for him to take accountability, he'd run his entire department over with a bus to save his own skin. Nothing was ever his fault. A missed deadline, a bad call, a dropped ball. There was always someone else's name attached to it by the time it reached the captain.

I watched this happen enough times that I could predict it before it happened. Something would go sideways, and within the hour, the story had already shifted. It was never a lie exactly. It was just a version of events that always, somehow, left him clean (at least in his own mind).

Habit Two: He Gossiped About His Own Team

He shared his negative opinions about team members with their colleagues. Gossip was one of his favorite pastimes. It didn't take long before people realized that whatever they said in confidence, or whatever mistake they made in private, might come back to them secondhand from someone else on the team.

That's a specific kind of damage. It's not just that people stopped trusting him. They stopped trusting each other, because nobody knew who he'd talked to, or what he'd said about them, or when it would surface.

Why This Destroys a Team Faster Than Yelling Ever Could

Neither of these behaviors looks like a crisis in the moment. That's exactly what makes them so dangerous. They erode trust quietly, decision by decision, conversation by conversation.

If you strip people of their dignity, they won't unite behind you. They'll unite against you, and quietly stop caring. That's a much harder problem to fix than a bad temper, because there's no single blow-up to point to.

What Made It Worse Than an Angry Boss

I've served under leaders with short tempers too. Strangely, those were easier to work for. You knew exactly where you stood, and you could plan around it.

This boss never gave you that. His pleasantness was the disguise — the same kind of surface calm that has nothing to do with the self-discipline that actually holds a team together. You never saw the blow coming, because there wasn't one. Just a slow accumulation of betrayals that announced themselves quietly.

Leadership Is a Skill, Not a Personality Trait

Leadership is the art of building trust, earning respect, and creating a culture of accountability. It's a skill you build deliberately, not a personality trait you either have or don't. This boss had a pleasant personality and nearly none of the skill.

• Owning a mistake (or taking ownership for a mistake your team made) costs much less than pointing fingers.

• What you say about one team member to another always gets back to them eventually

• Trust erodes silently long before anyone tells you it's gone

• A pleasant leader can still be destructive — tone isn't the same thing as integrity

Marching Orders

If your team doesn't feel safe bringing you their problems, that's not a communication issue. It's a trust issue, and it starts with you. If you want to get sharper on where you actually stand, take the free 3-minute leadership assessment. Your mission starts here.
